Abstract: Medical devices and systems for treating a stricture along the biliary and/or pancreatic tract are disclosed. An example medical device may include a guidewire for use along the biliary and/or pancreatic tract. The guidewire may include an elongate core member having a proximal end region and a distal end region. A coil member may be disposed along the distal end region. An actuation member may be coupled to the coil member. The actuation member may be configured to shift the coil member between a first configuration and a compressed configuration. The coil member may be configured to be advanced across a biliary and/or pancreatic stricture when in the compressed configuration. A sleeve may be disposed over the coil member.

Abstract: According to exemplary embodiments of the present disclosure, devices, systems, and methods for pyloric occlusion in an endoscopic procedure may include a first flange and a second flange connected to the first flange by a saddle region having a lumen. The second flange may be proximal to the first flange. The pyloric occlusion device may further include a closure element. The closure element may be configured to occlude a flow of material through the lumen, including across the pylorus when deployed. The closure element may be a closure of the lumen by rotation of one of the first or second flanges about the saddle region relative to the other of the first or second flange.

Abstract: Medical devices and methods for using medical devices are disclosed. An example medical device includes a scaffold including an inner surface, an outer surface, a proximal end region, a distal end region, a lumen extending from the proximal end region to the distal end region, and a retention member extending radially away from the outer surface. The retention member has a distally facing surface and a proximally facing surface. A membrane is disposed within the lumen of the tubular scaffold and is secured to the inner surface of the tubular scaffold at a first circumferential attachment region and at a second circumferential attachment region. Further, the membrane is unattached to the inner surface of the tubular scaffold between the first circumferential attachment region and the second circumferential attachment region to define a tissue ingrowth region between the inner surface of the tubular scaffold and an outwardly-facing surface of the membrane.

Abstract: A method for performing a medical procedure may comprise advancing a first device through a first body lumen. A distal portion of the first device may include a magnet. The method may further comprise advancing a second device through a second body lumen. The second device may include a magnetic field sensor. The method may further comprise receiving a signal from the magnetic field sensor. The signal may be indicative of a magnetic field measured by the magnetic field sensor. The method may further comprise, if the received signal matches a magnetic field of the magnet, identifying a position of the magnet.

Abstract: An elongate medical device is adapted to provide adjustable flexibility. The elongate medical device includes an inner coil having one or more inner coil filars extending in a first direction, and an outer coil having one or more outer filars extending in a second direction. A hypotube extends proximally from the inner coil and the outer coil. A cable extends through the inner coil and through the hypotube, where a distal end of the cable, a distal end of the inner coil and a distal end of the outer coil are all secured together at a distal end of the elongate medical device, such that applying a tensile force to the cable, relative to the hypotube, causes the inner coil and outer coil in combination to increase in stiffness.

Abstract: A tissue closure system includes an endoscope having first and second lumens therethrough, first and second control elements disposed within the first and second lumens, respectively, and a tissue engaging portion integral with a distal end of the endoscope. The tissue engaging portion includes a tissue acquisition assembly and a tissue closure assembly. The tissue acquisition assembly is controllable via the first control element, and the tissue closure assembly controllable via the second control element. The tissue engaging portion includes a tissue grasping portion for engaging first and second target tissue portions disposed adjacent an opening in target tissue. The tissue closure assembly is configured to pierce the target tissue, and to hold the first and second target tissue portions together to close the opening in the target tissue.
